The reactions of 1,1-diamino-2,2-diphenyl-substituted diphosphines featuring various degrees of P-P bond polarization with different alkynes were investigated. All diphosphines reacted with alkynes carrying one or two electron withdrawing carboxylic ester moieties under cleavage of the P-P bond and stereospecitic phosphinyl-phosphination at the triple bond to give unsymmetrical ethane-1,2-bisphosphines. Several of the products were further converted into chelate complexes upon reaction with group-10 metal dihalides, All isolated compounds were characterized by analytical and spectroscopic data, and several of the new ligands and complexes by single-crystal X-ray diffraction studies.
